In Lyon April 10-12

I am Natalia and I am going for SADECC fair in Lyon in Apr. Protected content . I have never been in your town before, so you can understand my excitement! which places would you recommend to visit/must-see in such a short visit? Also, any Internations events planned during that period maybe? ;)

If anyone would be up for a town walk/cup of coffee after work - I'll be more than glad to meet you :)
